CLion Offline Inspections Supported?

I'm trying to set up a CI process to run CLion inspections across my entire project and am running into some odd behavior, so I wanted to inquire if this is officially supported in CLion or if I may be missing something.

I'm using the standard inspect.sh workflow as outlined here

What I'm finding is that most of the beefier inspections (namely the clang-tidy based ones) only seem to function offline after the project has been opened in the GUI.  If I run offline inspections for a freshly pulled project (or blow away CLion's cache dir), offline inspection will speed through all files without running most inspections.  If I first open the project in the GUI, wait a moment, and then close it, subsequent offline inspections take much longer and seem to run the full set of inspections.

Is this a known issue or limitation, or is there a way I could get this to work without having to cycle the GUI like that?  I've currently got my CI task doing just that before running its inspections but that feels hacky & fragile.  I realize I could also just run clang-tidy directly myself, but it would be nice to be able to just have CLion handle it for consistency.
